TLDR
In this article, the long range transport of anthropogenic pollutants from the rest of Europe is the major source of Cd, Pb, and Zn in precipitation, and enrichment factors indicate anthropogenic origin, and Swedish atmospheric emissions of Zn and Cd are 2 to 3 times smaller than deposition fluxes.Abstract:
Trace metals (Cd, Cu, Fe, Mn, Pb, and Zn) concentrations in atmospheric precipitation have been routinely monitored in Sweden since the autumn of 1983. Concentrations are highest in southern Sweden and decrease northward. It is postulated that the long range transport of anthropogenic pollutants from the rest of Europe is the major source of Cd, Pb, and Zn in precipitation. Evidence for this hypothesis is that enrichment factors indicate anthropogenic origin, and Swedish atmospheric emissions of Zn and Cd are 2 to 3 times smaller than deposition fluxes. Also, Cd, Pb, and Zn concentrations are correlated in both space and time and are also well correlated with exSO4+, a substance known to be of anthropogenic origin transported long distances.read more

TL;DR: Additional work with fish is needed to better assess (1) the toxicity of aqueous metals in low-alkalinity waters, and (2) the toxicological significance of dietary methylmercury and cadmium.

Regional source discrimination of atmospheric aerosols in Europe using the isotopic composition of lead
TL;DR: In this paper, a series of daily atmospheric aerosol samples collected in southern Sweden between 9 February and 30 May 1988 were used to classify the samples according to source region: Northwest, Western Europe, East, Eastern Europe, or a combination of two regions.

On the use of mosses (Hylocomium splendens and Pleurozium schreberi) for estimating atmospheric trace metal deposition
TL;DR: In this paper, the authors compared trace metals in mosses Hylocomium splendens (Hs) and Pleurozium schreberi (Ps) along with wet deposition at 8 sites in Sweden.

Trace elements in atmospheric precipitation at Norweigan background stations (1989–1990) measured by ICP-MS
TL;DR: In this paper, the authors used ICP-MS to study 27 trace elements in precipitation at six rural and remote sites in Norway and found that the highest concentrations of elements associated with anthropogenic activities occur in northeastern Norway and in the southern part of the country (V, Pb, Ni, Cu, Zn, As, Mo, Cd, Sb).

TL;DR: In this paper, the authors studied the relationship between metal oxides and organic compounds and found that oxides are more likely to interact with organic compounds than with other organic compounds in the environment.

Atmospheric trace metals: global cycles and assessment of man's impact
TL;DR: In this article, the authors presented global data for sources of atmospheric input for 20 trace metals, and the relative importance of natural and anthropogenic sources is assessed, where interference factors are calculated as (total anthropogenic emissions/total natural emissions) × 100.

Trace metals in atmospheric deposition: A review and assessment
TL;DR: In this article, information on nineteen metals in atmospheric deposition potentially toxic to humans and other organisms was evaluated to conclude if metal concentrations are increasing in atmospheric deblurring and if these concentrations threaten human or organism health.
